    AC86U - httpd not responding

    I do have Diversion and Skynet running. No visible sign of any trouble there, both appear to be working fine. I did disable their "web integrations", but the problem occured again a few days later. I have also disabled them (via their respective menu options) AFTER the problem occurs, and...

    AC86U - httpd not responding

    Hi L&LD -- Thanks for the suggestions! Two different browsers on three different clients and two different OS.... Safari on iOS, and Edge on Windows. No extensions on Safari, it's plain vanilla. A couple extensions on Edge; I will try disabling those next time to see if there's any...

    AC86U - httpd not responding

    I have an AC86U with Merlin 386.3_2. It was setup "from scratch" after installing 386.3_2 and a full reset to defaults, a few months ago. Only additions are Diversion and SkyNet. There are about 40 active devices. NVRAM usage is 70168/131072. There is a 2gb swap file which was created by...

    Cyberpower UPS to power an RT-AX88U

    I can't answer, but maybe this thread will help: https://www.snbforums.com/threads/help-setting-up-nut-network-ups-tools-on-a-merlin-router.60084/

    A device with multiple clients?

    Several threads about this... Nobody knows the exact answer, but I can tell you that the message is misleading. What it really means is "This device's MAC address has been associated with more than one IP address." For example, it can be forced to happen by (1) Letting a device get an IP...

    Skynet Skynet - Router Firewall & Security Enhancements

    Not sure you noticed, and didn't see anyone else mention in replies.... Skynet has a cron job that removes all those "blocked" notices every hour, replacing them with a single line. So at most, there is "one hour's worth" of those messages at any given time, and they get cleaned out of syslog...

    Skynet Skynet - Router Firewall & Security Enhancements

    At least for me (in US, using Comcast DNS), global.chinadaily.com.cn resolves to 153.185.145.162. That IP is hosted in the US, according to iplocation.net info.

    2 clients are connecting to RT-AC87U through this device

    I've had it persist through reboots, too (I commented on that earlier somewhere in this thread). When looking for the cause on a specific MAC, I did find the two IP's -- the current active one, and the originally assigned one -- recorded in a file, "/jffs/nc/nt_center.db". Not sure if that is...

    2 clients are connecting to RT-AC87U through this device

    I've seen it persist long beyond my 24 hour dhcp lease time (i.e., it has shown up for days). And the "old" lease isn't displayed in the router's DHCP lease list. But it is certainly plausible -- and this could even differ between firmware versions I suppose -- that part of the cause is...

    Renaming Device doesn't save?

    I can't duplicate this, but my first guess would be a browser scripting problem. What browser are you using? Check the browser console for errors, or try a different browser?

    Trouble shooting to rule out router

    Yes, part of the call center "script" -- designed to confuse the customer by pointing fingers everywhere except the ISP themselves. :-)

    Trouble shooting to rule out router

    If DS power is >15, there is a plant/amp WAY out of adjustment and signal is likely distorted, and that's leading to the T3's (your modem probably isn't understanding the cmts responses because they are over-amplified and distorted). Your ISP is the only one that can fix it! Adding an...

    Trouble shooting to rule out router

    Coincidence. The router has no control over signal levels or negotiation with the CMTS.

    Trouble shooting to rule out router

    T3 timeouts are entirely related to negotiation between the modem and the CMTS. They cannot be caused by a separate router downstream from the modem. Usually they're the result of bad signal levels or interference (signal loss or noise injection), or very rarely a bad modem. On-site (your...

    Diversion Diversion - the Router Ad-Blocker

    That bypasses the browser's own cache. But I don't think it bypasses the OS cache? On windows, I usually run "ipconfig /flushdns" at command prompt to get rid of the OS's dns resolver cache. ** EDIT ** Ok, searched but couldn't find a definitive answer on this so I did some tests. This is on...

    Diversion Diversion - the Router Ad-Blocker

    Following the log for blocked domains is the correct way, but it can be challenging. For one thing, a page may refer to many blocked domains while only (1) of them is actually "breaking" the page. Trial and error is the only good way to solve that, as far as I know. Another problem is that...

    Diversion Diversion - the Router Ad-Blocker

    For UPS, try whitelisting this: ups.tt.omtrdc.net

    2 clients are connecting to RT-AC87U through this device

    Nope -- already tried that. Did not have any effect. I have completely emptied that "offline client list" multiple times, and still have devices showing "X clients are connecting" in Network Map. But what did just clear them all up.... I shut down my AP (88U with Ethernet backhaul running...

    2 clients are connecting to RT-AC87U through this device

    I haven't seen that issue, and am confused as to how it could happen. When blocking a device via parental control, an IPTables DROP rule is added for the MAC. I've tried this with devices that show "multiple devices are connecting" and the MAC is correctly added to the chain, thus successfully...

    2 clients are connecting to RT-AC87U through this device

    I have seen this on several devices.... I can intentionally create it by assigning a new (different IP) reservation for a device, then rebooting that device. When it gets the new IP, the count in the message is increased by (1) for that device. So it seems the message is really saying "there...
